Reading the gauges…

Follow Clarks Fork Yellowstone River for flow alerts

Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

About this

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.

2 official designations

Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.

Fish these abroad

About this

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.

At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.

A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.

Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: a point on the mapped channel of “Clarks Fork Yellowstone River”, halfway along its length in Wyoming, from the USGS high-resolution hydrography (NHDPlus HR), read 4 Nov 2026. It marks the water, not a particular access or reach. Water type is our own classification.
